Affected Genes Inferred by Location (0)

If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
In these cases, there will be no "Export to Hitlist" button to the left.

Phenotypic Data

In combination with other aberrations

The In(2R)bw^VDe2 pigmentation phenotype is suppressed by C(1;YL)w^mMc or In(1)w^m51b.

(Talbert and Henikoff, 2000)

The bw⁺ cis-effect in different inversion chromosomes is ranked: In(2R)bw^VDe1 > In(2R)bw^VDe2 > In(2R)bw^VK.

(Koryakov et al., 1998)

Position effect variegation (PEV) at the bw locus caused by In(2R)bw^VDe2 is dominantly enhanced by Dp(2;2)Mdh, and suppressed by Df(2R)en-A.

(Sinclair et al., 1998)

The position effect variegation at the bw locus caused by In(2R)bw^VDe2 is suppressed by Df(3R)Ace-HD1.

(Cleard et al., 1997)

The position effect variegation of bw caused by In(2R)bw^VDe2 is consistently suppressed by T(2;3)Sb^V, although In(2R)bw^VDe2 has little effect on the position effect variegation of Sb caused by T(2;3)Sb^V. In(2R)bw^VDe2 and C(1;YL)w^mMc, and In(2R)bw^VDe2 and In(1)w^m51b in combination show dominant suppression of variegation of one or both of w and bw, as measured by eye pigment levels. In contrast In(2R)bw^VDe2 and T(1;4)w^mJ in combination show enhancement of variegation of one or both of w and bw.

(Lloyd et al., 1997)

NOT in combination with other aberrations

Homozygous lethal.

(Koryakov et al., 1998)

Carnitine compounds (L-Carnitine, L-Acetylcarnitine and L-Propionylcarnitine) show a significant suppression on bw variegation. Butyrate gives a weaker suppression.
